pF (Note 4)
Note 4: CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating current consumption without load. Average
operating current can be obtained by the equation: ICC (opr) = CPD * VCC * fIN + ICC.
When the outputs drive a capacitive load, total current consumption is the sum of CPD, and ∆ICC which is obtained from the following formula:
CQ0–CQ3 and CTC are the capacitances at Q0–Q3 and TC, respectively. FCP is the input frequency of the CP.
